CHASSIS DE VEHICULE AUTOMOBILE
La présente invention concerne un châssis de véhicule automobile comprenant deux longeronnets latéraux entre lesquels s'étendent transversalement en y étant fixées la partie de plancher avant, la partie de plancher arrière, une traverse dite traverse planche à talon dont les bords longitudinaux supérieur et inférieur sont respectivement fixés aux parties de plancher avant et arrière et des moyens pour rigidifier la traverse planche à talon. MOTOR VEHICLE CHASSIS
The present invention relates to a chassis of a motor vehicle comprising two lateral beams between which extend transversely while being fixed therein the front floor part, the rear floor part, a cross member known as a heel board crosspiece whose upper and lower longitudinal edges are respectively fixed to the front and rear floor parts and means for stiffening the heel board cross member.
De nombreux développements récents sur l'aménagement intérieur de l'habitacle d'un véhicule automobile ont conduit à améliorer les agencements des différents éléments entre eux, tels que les sièges, dans celui-ci et leur cinématique dans le but d'augmenter à souhait la place disponible. Ainsi, dans les véhicules de type break dans lesquels on a cherché à implanter sept assises, différentes améliorations ont consisté à prévoir des banquettes arrières en partie escamotable, à implanter des sièges de type strapontin à l'arrière du véhicule, de préférence complètement amovibles de l'habitacle. Many recent developments on the interior layout of the passenger compartment of a motor vehicle have led to improving the arrangements of the various elements between them, such as the seats, in the latter and their kinematics with the aim of increasing at will. the space available. Thus, in station wagon vehicles in which we have sought to install seven seats, various improvements have consisted in providing rear seats that are partially retractable, in installing seats of the folding seat type at the rear of the vehicle, preferably completely removable from the cockpit.
Une amélioration intéressante pour les véhicules de ce type consisterait à proposer un véhicule avec sept assises individuelles dont cinq arrières seraient obtenus en deux rangées de sièges individuels modulaires et ce sans changer les dimensions connues pour les véhicules break. Pour ce faire, il apparaît absolument nécessaire de disposer d'un châssis avec un plancher le plus plat possible. En effet, la configuration actuelle des châssis dans les véhicules de type break ne permet pas An interesting improvement for vehicles of this type would be to offer a vehicle with seven individual seats, five of which rear would be obtained in two rows of modular individual seats, without changing the dimensions known for station wagons. To do this, it seems absolutely necessary to have a chassis with the flattest floor possible. Indeed, the current configuration of the chassis in station wagon vehicles does not allow

1 de loger des sièges individuels à l'arrière du véhicule car la hauteur disponible est insuffisante.
1 to accommodate individual seats at the rear of the vehicle because the available height is insufficient.
Le but de l'invention est alors de proposer un châssis de véhicule automobile qui permette d'obtenir un véhicule de type break avec sept assises individuelles dont cinq arrières seraient obtenus en deux rangées de sièges individuels modulaires. The object of the invention is then to provide a motor vehicle chassis which makes it possible to obtain a station wagon type vehicle with seven individual seats, five of which rear would be obtained in two rows of modular individual seats.
Pour ce faire, l'invention a pour objet un châssis de véhicule automobile comprenant deux longeronnets latéraux entre lesquels s'étendent transversalement en y étant fixées la partie de plancher avant, la partie de plancher arrière, une traverse dite traverse planche à talon dont les bords longitudinaux supérieur et inférieur sont respectivement fixés aux parties de plancher avant et arrière et des moyens pour rigidifier la traverse planche à talon remarquable en ce que les moyens de rigidification sont constitués d'une traverse de longueur sensiblement égale à celle de la traverse planche à talon qui s'étend en dessous du bord longitudinal inférieur de celle-ci en y étant fixé et dont chacune des extrémités est fixée à un des longeronnets latéraux. To do this, the invention relates to a motor vehicle chassis comprising two lateral beams between which extend transversely by being fixed therein the front floor part, the rear floor part, a cross called heel board crosspiece whose upper and lower longitudinal edges are respectively fixed to the front and rear floor parts and means for stiffening the heel board cross member remarkable in that the stiffening means consist of a cross member of length substantially equal to that of the board board cross member heel which extends below the lower longitudinal edge thereof being fixed thereto and each of the ends of which is fixed to one of the side beams.
La solution selon l'invention qui permet d'atteindre très facilement l'objectif recherché est loin d'avoir été évidente. En effet, l'homme de l'art qui cherche à obtenir directement un plancher le plus plat possible dans un véhicule de type break pense tout d'abord à enlever la pièce de hauteur importante disposée au-dessus de la traverse planche à talon. Or, enlever cette pièce appelée raidisseur planche à talon revient à réduire considérablement la rigidité du plancher. Cette réduction de The solution according to the invention which makes it very easy to achieve the desired objective is far from being obvious. Indeed, a person skilled in the art who seeks to obtain the flattest possible floor directly in a station wagon type vehicle first of all thinks of removing the piece of considerable height placed above the heel board cross member. However, removing this part called heel board stiffener amounts to considerably reducing the rigidity of the floor. This reduction of
<Desc/Clms Page number 3><Desc / Clms Page number 3>
rigidité conduit tout d'abord à l'affaissement localisé du plancher lorsqu'un passager prendrait place sur un siège arrière. Ensuite lorsque le véhicule automobile n'est plus statique, le plancher subit les variations d'effort sur le siège en fonction du profil de la route, des freinages et accélérations du véhicule. Ceci conduit à un phénomène dit de pompage du plancher ainsi qu'à des vibrations de la caisse dégradant fortement le confort vibratoire pour les passagers. rigidity first leads to localized sagging of the floor when a passenger takes a seat in a rear seat. Then when the motor vehicle is no longer static, the floor undergoes variations in force on the seat as a function of the profile of the road, the braking and acceleration of the vehicle. This leads to a phenomenon known as pumping of the floor as well as to vibrations of the body greatly degrading the vibratory comfort for the passengers.
Ainsi, l'homme de l'art confronté à ces difficultés techniques chercherait plutôt à redéfinir l'architecture du châssis et de son plancher associé. Thus, those skilled in the art confronted with these technical difficulties would rather seek to redefine the architecture of the chassis and its associated floor.
Au contraire, les inventeurs ont su judicieusement mettre en évidence que l'implantation d'une traverse en dessous de la traverse planche à talon permettait d'obtenir la rigidité supplémentaire désirée éliminant ainsi tout phénomène de pompage et réduisant les nuisances vibratoires précitées. En outre, elle permet une capacité de chargement accrue du véhicule break, objet de l'invention, lorsque les sièges individuels arrières sont complètement enlevés. On the contrary, the inventors were able to judiciously demonstrate that the implantation of a cross member below the heel board cross member made it possible to obtain the additional rigidity desired thereby eliminating any pumping phenomenon and reducing the above-mentioned vibration disturbances. In addition, it allows increased loading capacity of the station wagon, object of the invention, when the individual rear seats are completely removed.
Avantageusement, la traverse de rigidification est constituée de deux éléments assemblés entre eux de manière à former un corps creux. Advantageously, the stiffening crosspiece consists of two elements assembled together so as to form a hollow body.
De préférence, les deux éléments sont en tôle emboutie assemblés entre eux par soudure. Preferably, the two elements are in pressed sheet metal assembled together by welding.
De préférence encore, la traverse présente au moins un évidement adapté pour assurer le passage d'au moins un élément, tel qu'un tube d'échappement, entre ladite traverse et le plancher. More preferably, the cross member has at least one recess adapted to ensure the passage of at least one element, such as an exhaust tube, between said cross member and the floor.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
Selon un mode de réalisation préféré de l'invention, les moyens de fixation de la traverse de rigidification respectivement au bord longitudinal inférieur de la traverse planche à talon et aux longeronnets latéraux sont amovibles. According to a preferred embodiment of the invention, the means for fixing the stiffening cross member respectively to the lower longitudinal edge of the heel board cross member and to the side beams are removable.
Selon ce mode, les moyens de fixation de la traverse de rigidification au bord longitudinal inférieur de la traverse planche à talon sont des vis ou des équerres. According to this mode, the means for fixing the stiffening cross member to the lower longitudinal edge of the heel board cross member are screws or brackets.
Avantageusement et selon l'invention, la partie du plancher arrière comprend un panneau fixé au bord longitudinal supérieur de la traverse planche à talon et sur lequel est fixée une première traverse supportant l'avant de glissières de siège et au moins un panneau de charge sur lequel est fixée une deuxième traverse supportant l'arrière des glissières de siège. Advantageously and according to the invention, the part of the rear floor comprises a panel fixed to the upper longitudinal edge of the heel board cross member and on which is fixed a first cross member supporting the front of seat runners and at least one load panel on which is fixed a second cross supporting the rear of the seat rails.
L'invention concerne également un véhicule automobile de type break comprenant un châssis tel que précédemment décrit. The invention also relates to a station wagon motor vehicle comprising a chassis as previously described.
D'autres avantages et caractéristiques de l'invention seront mieux compris à la lecture de la description détaillée faite en référence au figures suivantes dans lesquelles : figures la et lb : une vue en perspective et une vue en coupe d'une partie d'un châssis d'un véhicule automobile selon l'état de l'art ; figures 2a et 2b : une vue avant et arrière en perspective d'une partie d'un châssis d'un véhicule automobile selon l'invention ; figure 3 : une vue en perspective d'une traverse selon l'invention. Other advantages and characteristics of the invention will be better understood on reading the detailed description made with reference to the following figures in which: Figures la and lb: a perspective view and a sectional view of part of a chassis of a motor vehicle according to the state of the art; FIGS. 2a and 2b: a front and rear perspective view of part of a chassis of a motor vehicle according to the invention; Figure 3: a perspective view of a crosspiece according to the invention.

Sur les figures la et 1b est représenté une partie d'un châssis 1 d'un véhicule automobile selon l'état de l'art. Ce châssis 1 comporte tout d'abord deux longeronnets latéraux identiques 21,22 qui s'étendent selon l'axe longitudinal du véhicule. In Figures la and 1b is shown a part of a chassis 1 of a motor vehicle according to the state of the art. This chassis 1 firstly comprises two identical side beams 21, 22 which extend along the longitudinal axis of the vehicle.
Un plancher 3 s'étend en y étant fixé entre ces deux longeronnets 21,22. Ce plancher comprend une partie avant 31 et une partie arrière 32 reliées entre elles par une traverse 4 dite traverse planche à talon par l'intermédiaire de soudures non représentées. A floor 3 extends by being fixed there between these two beams 21, 22. This floor comprises a front part 31 and a rear part 32 connected to each other by a crossmember 4 known as a heel board crossmember by means of welds not shown.
Chacune des deux extrémités de cette traverse planche à talon 4 est elle-même soudée à un des longeronnets 21,22. Each of the two ends of this heel board cross 4 is itself welded to one of the side members 21, 22.
La partie arrière 32 du plancher comprend, à proximité de la traverse planche à talon 4, un raidisseur en tôle 5 dont la forme et l'épaisseur permettent de rigidifier suffisamment cette dernière. The rear part 32 of the floor comprises, near the heel board cross member 4, a sheet metal stiffener 5 whose shape and thickness allow the latter to be stiffened sufficiently.
Sur la figure la, on voit que, pour assurer une rigidification suffisante à la traverse planche à talon 4, le raidisseur en tôle 5 doit avoir une hauteur importante de sorte que le dénivelé H existant entre la partie avant du plancher 31 et le sommet du raidisseur 4 est également important, généralement de l'ordre de 250 à 300mm. In FIG. 1a, it can be seen that, in order to ensure sufficient stiffening of the heel board cross member 4, the sheet metal stiffener 5 must have a significant height so that the difference in height H existing between the front part of the floor 31 and the top of the stiffener 4 is also important, generally of the order of 250 to 300mm.
Une partie d'un châssis 1 d'un véhicule automobile de type break selon l'invention est représentée aux figures 2a et 2b. La partie arrière 32 du plancher 3 selon l'invention comprend un panneau arrière 321 dont le bord longitudinal avant 3210 est soudé à celui supérieur 41 de la traverse planche à talon 4. Part of a chassis 1 of a station wagon motor vehicle according to the invention is shown in Figures 2a and 2b. The rear part 32 of the floor 3 according to the invention comprises a rear panel 321, the front longitudinal edge 3210 of which is welded to the upper one 41 of the heel board cross 4.
Sur ce panneau arrière 321 est fixée une première paire de supports de glissières de On this rear panel 321 is fixed a first pair of slide supports of
<Desc/Clms Page number 6><Desc / Clms Page number 6>
sièges 32a adaptée pour recevoir des sièges individuels modulaires. seats 32a adapted to receive individual modular seats.
La partie arrière 32 du plancher 3 selon l'invention comprend également deux panneaux de charge 322,323 soudés entre eux sur un de leurs bords longitudinaux, l'un de ces panneaux de charge 322 étant lui-même soudé par son bord longitudinal avant 3221 à celui arrière du panneau arrière 321 précédemment décrit. Sur chacun de ces panneaux de charge est fixé un support de glissière constituant une deuxième paire de supports de glissières de sièges 32b adaptée pour recevoir également des sièges individuels modulaires. The rear part 32 of the floor 3 according to the invention also comprises two load panels 322,323 welded together on one of their longitudinal edges, one of these load panels 322 itself being welded by its front longitudinal edge 3221 to that rear of the rear panel 321 previously described. On each of these load panels is fixed a slide support constituting a second pair of seat slide supports 32b adapted to also receive individual modular seats.
Une traverse de rigidification 51, représentée en figure 3, de longueur sensiblement égale à celle de la traverse planche à talon 4, s'étend en dessous du bord longitudinal inférieur de celle-ci 42 en y étant fixée, par l'intermédiaire d'équerres 6 amovibles placées dans des alésages 510. Chacune des extrémités 511, 512 de cette traverse 51 est fixée respectivement à un des longeronnets latéraux 21,22 par l'intermédiaire de vis non représentées placées dans des alésages 513 prévus à cet effet. A stiffening cross member 51, shown in FIG. 3, of length substantially equal to that of the heel board cross member 4, extends below the lower longitudinal edge thereof 42 by being fixed thereto, by means of 6 removable brackets placed in bores 510. Each of the ends 511, 512 of this cross member 51 is fixed respectively to one of the side beams 21, 22 by means of screws not shown placed in bores 513 provided for this purpose.
Cette traverse de rigidification 51 est constituée de deux plaques en tôle emboutie assemblées entre elles par soudure en formant un corps creux. This stiffening cross member 51 consists of two stamped sheet metal plates assembled together by welding to form a hollow body.
Le corps creux ainsi formé présente dans sa partie milieu un évidement (C) permettant le passage de la ligne d'échappement du véhicule automobile. The hollow body thus formed has in its middle part a recess (C) allowing the passage of the exhaust line of the motor vehicle.
La rigidité de ce corps creux est adaptée d'une part pour éliminer tout phénomène de pompage susceptible de se produire et d'autre The rigidity of this hollow body is adapted on the one hand to eliminate any pumping phenomenon likely to occur and on the other
<Desc/Clms Page number 7><Desc / Clms Page number 7>
part réduire au maximum les bruits et vibrations mécaniques susceptible de se propager au niveau de la traverse planche à talon 4. share reduce as much as possible the mechanical noises and vibrations likely to be propagated at the level of the heel board cross 4.
Avec une telle traverse de rigidification, le plancher 3 du véhicule est sensiblement plat sur toute sa longueur. Ainsi, Le dénivelé h existant entre la partie avant du plancher 31 et le panneau arrière 321 est faible de l'ordre de 150 mm. With such a stiffening cross member, the floor 3 of the vehicle is substantially flat over its entire length. Thus, the difference in height h existing between the front part of the floor 31 and the rear panel 321 is small on the order of 150 mm.
L'invention qui vient d'être décrite permet d'obtenir un véhicule automobile de type break avec un plancher le plus plat possible et dans lequel il est possible d'implanter sept sièges individuels modulaires. The invention which has just been described makes it possible to obtain a station wagon-type motor vehicle with the flattest possible floor and in which it is possible to install seven individual modular seats.
En outre, selon un autre aspect important de l'invention, la traverse de rigidification amovible et qui est proposée sans modification conséquente de l'architecture du véhicule permet de conserver le soubassement de celle-ci dans l'hypothèse où le véhicule à fabriquer est un véhicule de type berline ou monospace. En effet, dans une telle hypothèse, la traverse de rigidification 51 sera complètement enlevée du châssis selon l'invention et des moyens de rigidification connus en soi pourront être rapportés à l'intérieur de la caisse, l'absence de rangée supplémentaire de sièges arrières (véhicule de type berline) ou la hauteur de l'habitacle (véhicule de type monospace) le permettant. In addition, according to another important aspect of the invention, the removable stiffening cross member which is proposed without any consequent modification of the architecture of the vehicle makes it possible to conserve the base thereof in the event that the vehicle to be manufactured is a sedan or minivan type vehicle. Indeed, in such a case, the stiffening cross member 51 will be completely removed from the chassis according to the invention and stiffening means known per se may be added to the interior of the body, the absence of an additional row of rear seats (sedan type vehicle) or the height of the passenger compartment (minivan type vehicle) allowing it.
Bien entendu il va de soi que d'autres modifications et améliorations peuvent être apportées sans pour autant sortir du cadre de l'invention. Ainsi, le matériau constitutif et les dimensions de la traverse de rigidification peuvent être facilement adaptés en fonction des Of course it goes without saying that other modifications and improvements can be made without departing from the scope of the invention. Thus, the constituent material and the dimensions of the stiffening crosspiece can be easily adapted according to the
